Everyone has heard that good things come in small packages, but we set out to prove just how many good things you can fit into one.

We came up with a jacket you can wear year-round, as a layer in winter or a jacket in spring and fall and cool summer nights. The warmth comes from lofty 60-gram PrimaLoft One polyester insulation, along with ultralight ripstop nylon that helps resist wind and weather without restricting mobility. Elastic cuffs and a drawcord hem keep body heat from escaping.

The light-yet-dense materials we used to construct this jacket make it not only lightweight  it weighs just 12 ounces, less than a can of soda  but also highly compressible. The jacket packs into its own pocket to about the size of a water bottle, so it takes up minimal space in your pack, in your car or hanging on your coatrack  wherever you think you might need an extra layer.

Spring jacket, fall jacket, winter layer, wind and weather resistant shell, emergency jacket that fits just about anywhere  that's a lot for one small package, and for a lot less than you might expect.
